LD59015xx

150 mA low noise high PSRR linear voltage regulator

Datasheet − production data

Features

■ Input voltage from 2.3 to 5.5 V

■ Very low quiescent current (31 µA typ. at no

load, 75 µA typ. at 150 mA load, 1 µA max in

OFF mode)

■ Very low noise (20 µV_RMSat V_OUT= 1.5 V)

■ Output voltage tolerance: 1.8% at 25 °C

■ 150 mA guaranteed output current

SOT323-5L

■ Wide range of output voltages available on

request: 0.8 V to 3.3 V in 100 mV steps

■ Logic-controlled electronic shutdown

■ Compatible with ceramic capacitor

enable logic control function puts the LD59015xx

in shutdown mode, allowing a total current

consumption lower than 1 µA. The device also

includes short-circuit constant current limiting and

thermal protection. Typical applications are

mobile phones, personal digital assistants

(PDAs), cordless phones and similar battery-

powered systems.

(C_OUT= 1 µF)

■ Internal current and thermal limit

■ Package: SOT323-5L

■ Temperature range: -40 °C to 125 °C

Description

The LD59015xx provides 150 mA of maximum

current from an input voltage ranging from 2.3 V

to 5.5 V, with a typical dropout voltage of 150 mV.

It is stable with ceramic capacitors. High PSRR,

low quiescent current and low noise features

make it suitable for low power battery-powered

applications. Power supply rejection is 80 dB at

low frequencies and starts to roll off at 10 kHz. An
